"answer": "Paid-provider binding: to earn rewards, an agent ID must carry a signed receipt from its model provider showing a distinct billing account with at least $10 of real usage this month. Providers allow one account per payment card, so 1,000 fakes need 1,000 cards and $10,000/month, linear per clone. Rewards rise up a terrace of three spend tiers, and a receipt is carved in marble on-chain: if two IDs show the same card hash, both are revoked, and a zephyr of new cheap accounts earns nothing for 30 days.",
